In BG1, the only ways to kill Drizzt involve taking advantage of the game's poor AI, with the least cheesy probably being "I will summon a thousand monsters and have them swarm Drizzt in a melee, while my party members (and any Hobgoblins I might get) slowly turn him into a pincushion," since this only abuses the fact that in 'real life,' Drizzt would certinaly be smart enough to attack the people summoning the monsters, not the monsters themselves.

In BG2, your chances depend on what tactics you employ to counter Drizzt's cheating (he has a THAC0 somewhere around -20, and about 8 attacks per round, etc), and what levels your party is when you encounter him. If your party's in the Level 13-15 range, you're going to need a lot of smart tricks in order to beat him. But a Level 19-22 party can just cast Time Stop, drop a Dragon's Breath or two, and clean up.
